AI0-001 AI Security, Ethics and Governance Practice Question
A healthcare organization uses an AI model to predict patient readmission risk. To comply with patient privacy regulations, they apply differential privacy during training. What is the primary trade-off of using differential privacy?
⚠ Common exam trap
The AI0-001 exam often tests the misconception that differential privacy primarily reduces bias or improves fairness, when in fact its core trade-off is accuracy for privacy, and fairness can be negatively impacted by the added noise.

Correct answer & explanation
✓
Reduced model accuracy for increased privacy
Differential privacy works by adding calibrated noise to the training process or model outputs, which directly reduces the model's accuracy in exchange for a quantifiable privacy guarantee (e.g., ε-differential privacy). This trade-off is fundamental: stronger privacy (lower ε) requires more noise, which degrades predictive performance. The healthcare organization must balance the need to protect patient data against the clinical utility of accurate readmission predictions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increased training time for reduced bias
Why it's wrong here
Training time may increase, but bias reduction is not the primary trade-off.
- ✗
Lower interpretability for higher fairness
Why it's wrong here
Interpretability and fairness are not directly traded off with differential privacy.
- ✗
Faster inference for lower memory usage
Why it's wrong here
Inference speed and memory are not significantly affected.
- ✓
Reduced model accuracy for increased privacy
Why this is correct
Noise injection lowers accuracy but bounds privacy loss.
